It's a very old Taiwan romance novel. I don't remember the names of the male and female protagonists. It's probably about a female protagonist

The female CEO and the male CEO were just ordinary employees. The two of them had gotten to know each other through a misunderstanding. The female protagonist accidentally fell into the water at a company party. A male employee rescued the female protagonist and took care of her until she recovered. The female protagonist gradually discovered that the male employee had special feelings for her, but she did not know if her feelings were valid. At a company meeting, the female protagonist was accused of poor management. The male employee defended the female protagonist, and the misunderstanding between the two deepened. In the end, the female lead decided to leave the company and leave the male employees. However, the male employee did not give up. He expressed his feelings to the female lead in various ways. In the end, the two of them resolved the misunderstanding and got together.
